javascript - AngularJS 无法设置文本区域的值

Question

我试图为表单中的某些元素设置默认值，虽然它适用于所有输入字段，但它似乎不适用于文本区域，而代码几乎相同。

表单的 HTML:

<form class="form-horizontal" id="infoForm" name="form" ng-submit="ctrl.submitInfoForm(form)" novalidate>
    <div class="form-group">
        <label for="inputEditName">Name</label>
        <input type="text" class="form-control" value="{{ctrl.viewedName}}" id="inputEditName" ng-model="viewUser.name">
    </div>
    <div class="form-group">
        <label for="inputEditLocation">Location</label>
        <input type="text" class="form-control" value="{{ctrl.viewedLocation}}" id="inputEditLocation" ng-model="viewUser.location">
    </div>
    <div class="form-group">
        <label for="inputEditWebsite">Website</label>
        <input type="text" class="form-control" value="{{ctrl.viewedWebsite}}" id="inputEditWebsite" ng-model="viewUser.website">
    </div>
    <div class="form-group">
        <label for="inputEditBio">Bio</label>
        <textarea rows="3" class="form-control" id="inputEditBio" ng-model="viewUser.bio" >{{ctrl.viewedBio}}</textarea>
    </div>
    <button type="submit" class="btn btn-default">Save Changes</button>
</form>

ProfileController.js 的相关部分:

var vm = this;
vm.getViewedName = getViewedName;
vm.getViewedLocation = getViewedLocation;
vm.getViewedWebsite = getViewedWebsite;
vm.getViewedBio = getViewedBio;
vm.viewedName = getViewedName();
vm.viewedLocation = getViewedLocation();
vm.viewedWebsite = getViewedWebsite();
vm.viewedBio = getViewedBio();

function getViewedName() {
    if (vm.viewedName === undefined) {
        var viewedName;
        var viewedUser = UserService2.getViewedUser();
        viewedName = viewedUser.name;
        if (viewedName === "") {
            viewedName = "-";
        }
        return viewedName;
    } else {
        return vm.viewedName;
    }
}

function getViewedLocation() {
    if (vm.viewedLocation === undefined) {
        var viewedLocation;
        var viewedUser = UserService2.getViewedUser();
        viewedLocation = viewedUser.location;
        if (viewedLocation === "") {
            viewedLocation = "-";
        }
        return viewedLocation;
    } else {
        return vm.viewedLocation;
    }
}

function getViewedWebsite() {
    if (vm.viewedWebsite === undefined) {
        var viewedWebsite;
        var viewedUser = UserService2.getViewedUser();
        viewedWebsite = viewedUser.website;
        if (viewedWebsite === "") {
            viewedWebsite = "-";
        }
        return viewedWebsite;
    } else {
        return vm.viewedWebsite;
    }
}

function getViewedBio() {
    if (vm.viewedBio === undefined) {
        var viewedBio;
        var viewedUser = UserService2.getViewedUser();
        viewedBio = viewedUser.bio;
        if (viewedBio === "") {
            viewedBio = "-";
        }
        return viewedBio;
    } else {
        return vm.viewedBio;
    }
}

默认情况下仅设置名称，因此此时它看起来像这样:

姓名:我的名字地点: -网站: -简介:

Answer 1

我发现我做错了什么

首先，我有一个 ngModel 和附加到文本区域的 Controller 字段(以及其他输入)，所以我删除了该字段，现在我只使用 ngModel。

其次，我忘了按 ctrl。在我的 ngModel 属性中。我通过简单地添加 ctrl 来改变这一点。到我的 ngModel 属性。

所以我已经改变了一切，它现在可以工作了，看起来像这样:

HTML:

<form class="form-horizontal" id="infoForm" name="form" ng-submit="ctrl.submitInfoForm(form)" novalidate>
    <div class="form-group">
        <label for="inputEditName">Name</label>
        <input type="text" class="form-control" id="inputEditName" ng-model="ctrl.viewUser.name">
    </div>
    <div class="form-group">
        <label for="inputEditLocation">Location</label>
        <input type="text" class="form-control" id="inputEditLocation" ng-model="ctrl.viewUser.location">
    </div>
    <div class="form-group">
        <label for="inputEditWebsite">Website</label>
        <input type="text" class="form-control" id="inputEditWebsite" ng-model="ctrl.viewUser.website">
    </div>
    <div class="form-group">
        <label for="inputEditBio">Bio</label>
        <textarea rows="3" class="form-control" id="inputEditBio" ng-model="ctrl.viewUser.bio" ></textarea>
    </div>
    <button type="submit" class="btn btn-default">Save Changes</button>
</form>

ProfileController.js:

var vm = this;
vm.getViewedUser = getViewedUser;
vm.viewUser = getViewedUser();


function getViewedUser() {
    if (vm.viewUser === undefined) {
        vm.viewUser = UserService2.getViewedUser();
        if (vm.viewUser.name === "") {
            vm.viewUser.name = "-";
        }
        if (vm.viewUser.location === "") {
            vm.viewUser.location = "-";
        }
        if (vm.viewUser.website === "") {
            vm.viewUser.website = "-";
        }
        if (vm.viewUser.bio === "") {
            vm.viewUser.bio = "-";
        }
        return vm.viewUser;
    } else {
        return vm.viewUser;
    }
}

而Founded1898的答案以及 Vinod Louis 的评论有帮助，我觉得那些并没有完全回答我的问题，这就是我添加这个答案的原因。
